The LMV721M5/NOPB is a high-performing monolithic instrumentation amplifier that helps improve the accuracy and results of various electronic applications. It simplifies traditional methods of analog circuitry manufacture, especially in instrumentation and signal conditioning. This is a single-supply instrumentation amplifier, which provides a low-cost and effective solution for systems that rely on long battery life for their power source.

The LMV721M5/NOPB application field covers a variety of different industries, from consumer applications such as audio systems and medical diagnostics, to industrial processes such as automated machine control. This instrumentation amplifier is suitable for signal conditioning and data acquisition for both precision and low-level measurements. It is also suitable for auto-calibration routines, and can be used accurately without calibration in calibration-free applications.

This instrumentation amplifier was designed with a series topology, to provide a very high common-mode rejection ratio at higher gains, while maintaining a low quiescent current. It is a single-ended device, so it can be used with single-ended input signals, and both single-ended and differential output signals. The wide supply voltage range and low quiescent current ensure improved energy efficiency in power-constrained applications.

The working principle of the LMV721M5/NOPB is based on the the use of the three op amps, which provide high-precision gain and common-mode rejection ratio. The three op amps are configured as an inverting gain stage, an integrating stage and a non-inverting gain stage. The non-inverting gain stage provides the desired feedback for the two integral stages, and also provides a gain for the summed input. The integrating stage is responsible for integrating the signal, as well as canceling low-frequency noise. Finally, the inverting gain stage provides the necessary gain, as well as increasing the gain at the same time.

The wide supply voltage range and low passband distortion makes the LMV721M5/NOPB suitable for use in applications requiring high accuracy and performance. Combined with its wide bandwidth, high common-mode rejection ratio and low quiescent current, the LMV721M5/NOPB is perfectly suited for use in precision instrumentation and signal conditioning applications.
